Newer antihistamines like Allegra and Claritin are generally safe for daily use. But allergy medications with decongestants, such as Claritin-D or Benadryl-D, could make your allergies worse with long-term use.

Yes, you can take fexofenadine (Allegra) only when you need it if you have allergy symptoms once in a while. But if you have allergy symptoms on a daily basis, taking it regularly is more likely to give you the most relief from your allergies.

Each capsule contains 60 mg fexofenadine hydrochloride and the following excipients: croscarmellose sodium, gelatin, lactose, microcrystalline cellulose, and pregelatinized starch.

Trials have shown both Allegra (fexofenadine) and Claritin (loratadine) are significantly more effective than placebo (a pretend pill) for reducing symptoms associated with allergic rhinitis, hay fever, and other allergies.

If you want to be sure your allergy medication won't impair your everyday functioning, take it at night before you go to bed - or take fexofenadine (Allegra) (1%–3%), which is the least likely to make you drowsy.

Newer antihistamines like Allegra and Claritin are generally safe for daily use. But allergy medications with decongestants, such as Claritin-D or Benadryl-D, could make your allergies worse with long-term use.

Take the Allegra disintegrating tablet on an empty stomach, at least 1 hour before or 2 hours after a meal. Tell your doctor if your symptoms do not improve, or if they get worse after you start taking Allegra. Never use more than the recommended dose.

While it's generally well tolerated, it may cause side effects for some people. Common Allegra side effects include headache, indigestion, and dry mouth. Very rarely, people may experience drowsiness or fatigue after a dose. Side effects from Allegra are usually mild and can be managed at home.
